Spatial autocorrelograms for two Belgian (Waardebroeken, Kloosterbos) and two German (Bertsdorf, Hofeberg) populations of P. officinalis of morph-joins and Nasons’s kinship coefficients. (A) Results of the join count analyses for L-L (black circles) and S-S (white circles) joins, separately. Positive Z-values indicate higher aggregation whereas negative Z-values indicate negative spatial autocorrelation. Asterisks indicate significant deviations of random morph distribution (zero line) in a particular distance class. (B) Results of the genetic autocorrelation analyses. The solid line without symbols represents the correlogram for the entire population with the dashed lines indicating upper and lower 95% confidence intervals obtained after 10,000 permutations. Circles represent average multilocus kinship coefficients for the L-morph (black) and the S-morph (white), separately.
